About Zinc Oxide Powder

Zinc Oxide Powder is an inorganic compound represented chemically as ZnO. It appears as a fine, white powder that is insoluble in water and typically has a purity exceeding 99%. Supplied in micron- or nano-scale particle sizes, this powder is formulated for industrial use with particle distribution tailored to application requirements. Its strongly alkaline nature in aqueous suspension (pH 9-11) is a critical factor for its roles in polymer cross-linking and cosmetic formulations. Procurement professionals should note that Zinc Oxide Powder is sensitive to acidic materials, which may degrade its efficacy, and it should be handled and stored under controlled conditions to maintain quality. Typical dosage rates in rubber vulcanization range from 3% to 5% by weight of the rubber compound, reflecting its role as an activator in curing systems. This product is supplied in bulk bags or multi-layer paper bags for industrial-scale use.

Why Zinc Oxide Powder Matters

In the rubber industry, Zinc Oxide Powder acts as an essential activator in the vulcanization process, enabling polymer chains to form cross-links and improving material elasticity and thermal stability. This directly affects the durability and lifespan of rubber products such as tires and seals. In coatings and pharmaceutical formulations, Zinc Oxide provides protective qualities against ultraviolet radiation and microbial contamination, ensuring performance consistency and user safety. Using Zinc Oxide supports manufacturing processes that deliver enhanced product safety, longer service life, and better compliance with regulated quality standards.
